Exploration Insights Magazine - Last Issue for 2017

/Portals/1/Images/IEnergyImages/Exploration%20Insights/Cover_11_magazine_sized.pngThis month the Exploration Insights magazine takes you on a journey from the Arctic to northern South America and finishes on the west coast of Africa. On the way the risks of the Triassic reservoirs of the Norwegian Barents Sea are explored, the value of geochronology data interrogated and the hunt for the Late Cretaceous plays on the African Atlantic margin continues. This is rounded off nicely with an introduction to Brain Harland: one of the great “all-rounders” of geology.

 

THE NORWEGIAN BARENTS SEA: UNDERSTANDING TRIASSIC RESERVOIR RISK

The Norwegian Barents Sea is thought to have great potential for exploration, but success has been limited by issues with reservoir quality and effectiveness. The use of source to sink methodologies and depositional environment mapping, integrated with a better understanding of diagenesis, burial and uplift, all within a regional depth framework, highlight areas where reduced reservoir risk may be encountered.

 

APPLYING SOURCE TO SINK IN NORTHERN SOUTH AMERICA

The relatively recent growth in the quantity of accurate geochronology data in the public domain has enabled much more detailed characterisation of sediment sources and sinks. The usefulness of this approach and its application to understanding regional petroleum geology is demonstrated with an example from Miocene reservoirs in northern South America.

 

THE SEARCH FOR LATE CRETACEOUS PLAYS: GABON TO ANGOLA

Targeting Late Cretaceous coarse-grained clastic plays has resulted in notable exploration successes on the West African Transform Margin; we have evaluated the potential for similar plays in the deep water offshore from Gabon, south to Angola. Play element prediction and play identification can be augmented using a framework produced through collaboration between Landmark Exploration Insights (“Landmark”) and PGS.

 

GREAT GEOLOGISTS: BRIAN HARLAND

One of the great “all-rounders” of geology, Brian Harland carried out decades of research in the Arctic and used the knowledge gained to develop theories of global Pre-Cambrian glaciation and global geodynamics. He was a leading force in international geoscience collaboration, one aspect being the progressive development of the geological timescale.
